Brake help / question

Does anyone know what this means ? An if so how do I fix it ?

C0278
Open or Short Circuit in ABS Solenoid Relay Cirouit

 

Essentially you need to check powers and grounds at the ABS module (Skid Control ECU), if they are good but the code still sets then the ABS module (Skid Control ECU) has failed.
I can grab you a wiring diagram and pinout but I need to know if your truck has VSC or not.

 

Sorry but what in the world does VSC stand for ?

 

When I get this code I check power constant, ignition, grounds, can com, then lastly a physical corrosion check.

It's 999/1000 the ABS unit.

Pricy sadly.

Vehicle Stability Control.

If you have this button your truck has VSC if you don't then it doesnt.

 

That’s what I was afraid of.

 

Definitely don’t have that. Thank you for your reply.

 

It does not have VSC. Thank you

 

Here you go, I would reccomend using a test light to check the powers & grounds and be sure not to jam anything into the terminals when testing.

 

Thank you very much

 

I’ve pulled both fuses to the ABS unit. I would have thought that would have killed the ABS unit an gave me some brakes back. Guess I was wrong. Lol on a Chevy it works like that. Lol Would you still think the ABS unit is my cause ?
